Abstract

Disclosed is an inductive miniature structural element, particularly an antenna. Said structural element comprises a winding member ( 1 ) which is embodied as a flat component and on which three coil windings ( 2 X, 2 Y, 2 Z) are mounted in such a way that the axes of said coil windings point in the three three-dimensional directions (X, Y, Z). The winding member ( 1 ) is made at least in part of ferrite material while the top face and the bottom face thereof are provided with guiding elements ( 1.5, 1.6, 1.7, 1.8 ) for directing the third coil winding. The winding member ( 1 ) is placed on a coil plate ( 3 ) made of electrically non-conducting, non-ferromagnetic material and is connected thereto. The coil plate ( 3 ) is provided with recesses into which the guiding elements that are located on the bottom face of the winding member ( 1 ) engage. The ends of the first and second coil winding ( 2 X, 2 Y) are wound around the guiding elements located on the bottom face of the winding member, respectively, while the ends of the third coil winding ( 2 Z) are wound around corners or projections of the coil plate ( 3 ), respectively.
